Three major wireless carriers have joined up to popularize contactless payments in the US: AT&T, Verizon and T-Mobile. This is said to already be a big deal in Japan, where technology is king, but has yet to catch on in the States.

It's reported that the aforementioned companies will soon be testing these payment options in four cities, including Atlanta. This will be made possible through a partnership the carriers have set up with Discover Financial Services and Barclays Plc of Britain.

According to Engadget, such a technology would mean new readers for merchants as well as NFC chips in smartphones.

We wonder if many users will feel a bit reluctant to adopt the new technology, because as it seems, people are already very careful about their credit card information.
